What is the XMLRPC module?

This is a module which allows you to create a local XML-RPC server and/or to make calls on remote XML-RPC servers.

What is XML-RPC?

XML-RPC is a spec and a set of implementations that allow software running on disparate operating systems, running in different environments to make procedure calls over the Internet. It uses HTTP as the transport and XML as the encoding. XML-RPC is designed to be as simple as possible while allowing complex data structures to be transmitted, processed and returned.

Using XMLRPC

Here is an example:

The Server

It's really easy to set up a server which provides a set of remotely callable functions.

Create a server object

Add some methods

Start the server

You're done!

The Client

It's pretty easy to make the remote calls too

Create a proxy object to represent the remote server

Call the remote method via the proxy

That's all you need
